Abstract:

This paper tried to explore the comprehensive evaluation system of regional urban land intensive utilization from land use intensity, land use investment, land use benefit,etc. Based on the actual conditions, using principal component analysis and clustering analysis, this paper made comprehensive evaluation on the intensive land-use level of Shandong Province, analyzed the changing situation in space and time, provided reference for macro guidance in urban land intensive use and changing land use pattern. The results showed: (1) The level of urban land intensive use of Shandong Province constantly improved from 2000 to 2005, while decreased a little in 2006; (2) the level of urban land intensive use declines from coastal cities to inland cities, with the southwest cities having the lowest level; and (3) economic development level is the most important external factor affecting the level of urban land intensive use. The level of urban land intensive use is higher in developed areas, like Jinan and Qingdao, than other areas.

Key words: intensive evaluation, regional spatial-temporal difference, urban land use
